Final answer:
A tornado is an example of a weather event.
Step-by-step explanation:
An example of a weather event is a tornado. Tornadoes are powerful, rotating columns of air that are formed during severe thunderstorms. They can cause significant damage by destroying buildings, uprooting trees, and creating a path of destruction.
Unlike earthquakes, which are caused by the movement of tectonic plates, tornadoes are a weather phenomenon that occur when there is a combination of warm, moist air at the surface and strong wind shear in the atmosphere.
Other options listed in the question, such as earthquakes, mountain formation, and soil erosion, are not considered weather events but are related to other geological processes.
